Method for improving color temperature consistency of flat panel television through multiple gamma curves

Abstract

The invention discloses a method for improving the color temperature consistency of a flat panel television through multiple gamma curves, and relates to the field of flat panel television flat screen modules. The method comprises the following steps that the color temperature range of screen modules adopted by the flat panel television is determined; the color temperature range of the screen modules is graded; gamma debugging is conducted on screen module samples within each color temperature grade to enable the debugged color temperatures to be within the required color temperature range; the correspondingly-debugged gamma curves are combined into television software; the color temperature grades of all the screen modules on a production line are determined through testing, and the corresponding gamma curves are selected from the television software to complete subsequent production. According to the method, on the basis that the cost of existing flat panel televisions and screen modules is not increased, the displayed color temperatures are all controlled to be within the required range after the flat panel televisions with the same type of screen modules are produced, and therefore the color temperature consistency is improved.

Description

technical field [0001] The invention relates to the field of flat-panel TV flat-screen modules, in particular to a method for improving the color temperature consistency of flat-panel TVs by using a plurality of gamma curves. Background technique [0002] As competition in the flat-panel TV market intensifies, in order to reduce costs, various manufacturers have caused large differences in color temperature among screen modules of the same type. According to the traditional method, if one gamma curve is used for all screen modules of the same model, there will be large color temperature differences on flat-panel TVs, which will not only affect the subjective effect of TVs, but also affect the sales of TVs. If the color temperature consistency of the screen module is improved through the components used in the front-end control screen module, it means that the cost will increase significantly. Contents of the invention [0003] The object of the present invention is to add...

According to the traditional method, if one gamma curve is used for all screen modules of the same model, there will also be large differences in color temperature on flat-panel TVs, which will not only affect the subjective effect of the TV, but also affect the sales of the TV.

If the color temperature consistency of the screen module is improved through the components used in the front-end control screen module, it means that the cost will increase significantly
